To @ZZV/whom t may concern f1 i Beit known that I, WILLIAM H. Bor, a.

citizen of the` United States, residing at Ghent, in the countyv of Lyon and State of Minnesota, have invented certain new Yand useful Improvements in Separatore; and I do hereby kdeclare the following to be a full,

clear, and exact description of the invention,

legs. :The sides of 'the hopperare extended -or'opene,d, vmorefor less-,by agate or 'valve' such as will enable others skilled in theart to which it appertains'to make and yuse'the same. Y

My invention has for its objectto-proyvide an improved grain separator ofy theY type generally knownas fanning mills, and

which is especially adapted for the separa`- tion of succotash. So-called succotash is a mixture of wheat, .tame'oats,.and usually .Y

more or less of various other foreignseeds and materials, such as vwild oats, cockle,`

mustard seed, chaff, dust, etc.

This improved fanning mill will not only.

take the tame Oats, wild oats, cockle, chaff, dust, etc., out of good ',wheat, but will separate the tame oats and wildoats from eachl Vforeign materialsL other and remove other from both thereof.

A machine embodying the'several features of myinvention is illustrated in the accom-ffanning mill with some parts broken away;Y

Fig. 2 is aside elevation of the same;

Fig.v 3 is a vertical' section -taken approximately on thefline 3,-3 of Fig. 1;

- Fig. 4 is a detail view in sectiontaken on the line 4 4 of Fig. 3, on an enlarged scale; and

`Fig. 5 is a detail view in section taken on the line 5 5 of Fig. 3,'on an enlarged` scale.

A suitable framework, 4as shown, coinl prising oblique legs 4 and lower side boards 5,v at its uppermost portion 'supports'the feed hopper 6, and which hopper serves to braceand tie together the upper ends of the said and support a fan "casing 7 4which:haslan oblique downwardly 'extended discharge spout 8. In the bottom of the hopper' isa dischargev opening V9-adapted to be closed f l Specication of Letters Patent.

hopper and arranged to be operated by a.

rod 11, the free end of which is frictionally held in various adjustmentsr by the fork.

spring jaw offa bracket 12, also shown-as applied to the bottom of the hopper. The

. hopper discharge passage 9 delivers onto the are'preferably perforate zinc screens, the

lower members being indicated by the numeral 15 and all being carri-ed by a vibra-f tory shoe 16.*v This shoe 16 is arranged to vibrate longitudinally of the machine and,y

its rear or inner end portion is suspended by a 'pair' of links 17 pivotally connected thereto and to the sidesv` of the hopper. The front or outer end portion of said shoek is pivoted to the upper ends of a pair of laterally spaced levers 18 that are intermediately pivoted to the front legs r4.- The shoe 16- 10 shown as hinged tothe bottom lof the Y has an imperforate bottom deck 19 that inclines in reverse directions from its intermediate portion, so that the front portion delivers forwardly or outwardly and the inner portion thereof, deliversfbackwardly or inwardly and onto anendless apron 20. This apron 20 has a'fuzzy surface so that it will catch and carry upward, wild oats in particular, but also certain other objects. Preferably, the said apron is made of cotton flannel and it is arranged to run over an inofsheet metal, is a rigid part of'y a supple- Y mental frame 24 and the said rollers 22 and 23 are journaled therein. This supplemental frame 24, at-.its upper end, is hinged on laterally spaced links 25 pivoted thereto and to the extended sides Of the hopper, and yat its lower end, has laterally. spaced rigid arms 26 that are pivotally connected to the `lower `portions of the laterallyspaced levers 18. The said supplemental frame is thus mounted for oscillatory vmovements longitudinally of the machine. w

i The side `members of the supplemental frame 24 have at their upper and lowery edges removable sections'24aL held in 4positionpby screws or other suitable -means Formed partlyfin each side member ofthe supplemental frame 24 and partly in the removable tend tangentially.
